National Insect Week returns in 2020

Lesser Marsh Grasshopper Singing

Grasshoppers make sounds by rubbing their hind leg, which has pegs on it, on a thickened part of their forewing. The sounds are different for different species and can be used to identify the insects from a distance. The recording made here is of a Lesser Marsh Grasshopper (Chorthippus albomarginatus) on the bank of the River Humber in East Yorkshire and was made using an audio microphone.

Most poisonous

There are lots of contenders here – possibly the pretty red and blue rove beetle Paederus – very, very tiny amounts of its poison have been used to cure chronic ulceration in people. Ladybirds are pretty poisonous (and pretty) and can bleed foul-tasting poisonous brightly coloured blood from their knees.
